How to Find the Factors of 123
For finding factors of 123, we will be learning these below-mentioned methods:
- Multiplication Method
- Division Method
- Prime Factor and Prime Factorization
- Factor Tree
Finding Factors using Multiplication Methods
This particular method often finds the pair of factors which, on multiplication together, produces 123. Let us find the pairs which, on multiplication, yields 123.
- 1×123=123
- 3×41=123
So, factors of 123 are: 1,3,41, and 123.
Finding Factors using Division Method
The division method finds the factors that evenly divides the given number 123. In this process, we have to divide 123 by all possible natural numbers less than 123 and check.
1,3,41, and 123 are the only factors that the number 123 has. So to verify the factors of 123 using the division method, we just need to divide 123 by each factor.
123/1 =123
123/3=41
123/41=3
123/123=1
Prime Factors and Prime Factorization
Prime Factorization is the easiest process to find prime factors. It decomposes 123 into a product of its prime integers.
- Prime Factors of 123: 3,41.
- Prime Factorization of 123: 3×41
Factor tree
The number 123 is written on top and two branches are extended.
Fill in those branches with a factor pair of the number above, i.e., 123.
Continue this process until each branch ends with a prime factor (number).
The first two branches of the factor tree of 123 are 3 and 41.
Factor Pairs
Positive pair factors: (1,123), (3,41).
Negative pair factors: (-1,-123), (-3,-41).
